Abstract: A bearing assembly suitable for use in conjunction with x-ray device having a rotating target anode and electron source disposed in an evacuated enclosure. The bearing assembly includes a shaft having a rotor hub to which the anode is mounted. The shaft cooperates with front and rear bearing rings to define front and rear races, and a spacer facilitates positioning of the bearing rings. Front and rear ball sets are confined in the front and rear races, respectively. A bearing housing receives the bearing rings, spacer, front and rear ball sets, and part of the shaft. Finally, a magnet is disposed near the front bearing ring to prevent escape of foreign matter from the bearings and to prevent ingress of foreign matter to the bearings. Consequently, the magnet serves to extend the life of the bearings and to prevent foreign matter related arcing of the target anode and electron source.

Abstract: A bearing assembly mounted in an x-ray tube includes a bearing race and a plurality of bearing balls positioned adjacent to the bearing race. The plurality of bearing balls are positioned within a bearing cage. The bearing cage is configured to evenly space the bearing balls within the bearing cage and prevent contact between adjacent bearing balls, thereby eliminating the problems of skidding wear and dynamic impact load between adjacent bearing balls in the bearing assembly.

Abstract: In a first rolling bearing of this X-ray tube apparatus, an ion nitriding layer is formed on a raceway surface of an inner ring, and an ion nitriding layer is formed on a raceway surface of an outer ring. As the results, surface hardness of the raceway surface of the inner ring and the raceway surface of the outer ring is enhanced, and abrasion resistance can be improved. On the other hand, in a second rolling bearing, an ion nitriding layer and a diamond-like carbon film are successively formed on a raceway surface of an inner ring, and an ion nitriding layer and a diamond-like carbon film are successively formed on a raceway surface of an outer ring. As the results, the second rolling bearing which is positioned closer to the target has a double hardening structure.
